Freezer shows E17 and may not recognize door open/close state correctly; interior light may stay on.

Safety first: Unplug the freezer before working on the door switch or light wiring.

• Test door switch: Locate the door switch in the frame. Remove it and test continuity with a multimeter while pressing and releasing it. Replace if it does not change state.
• Inspect light module: Remove the interior light cover and check for signs of overheating or shorting.
• Check wiring: Follow the wires from the switch and light back to the control board, looking for pinched or damaged insulation.
• Replace faulty parts: Install a new Candy-compatible door switch or LED light module as needed.
• Verify operation: After reassembly, plug in the freezer and confirm that the light turns off when the door is closed and that E17 is cleared.

Warning: Do not bypass the door switch; it may affect defrost and alarm logic.
